TO PICK OR NOT TO PICK?

Every year I say to myself, "Next year I'll keep a garden diary". I never do. That's why I can't remember when I usually harvest these.

My mind tells me that I usually pick them the last week in June or first week in July. I'm sure that they usually look greener than this when harvested, but that may be because the saw fly hasn't denuded the bush of all it's leaves as usually happens and so they look yellower against the green foliage. I quite fancy a gooseberry crumble, but are they ready yet?
